Liftech helped design this Mitsui Engineering and Shipbuilding Co., Ltd. barge crane with a rotating boom and headblock for Matson. The headblock hangs from a rotating hoist platform. During normal operations, when the boom rotates, the headblock rotates relative to the boom so that the headblock does not rotate relative to the vessel.
Liftech assisted Sydney International Container Terminals Pty Ltd with structural design and review of four post-Panamax ZPMC low profile shuttle boom cranes for their new container terminal across from an airport in Sydney, Australia.
Liftech participated with APM Terminals to conceptualize and design FastNet, a crane technology that enables STS gantry cranes to work adjacent, instead of alternate, bays of a large container ship. APMT estimates that FastNet can deliver berth productivity of 450 moves an hour.
Felixstowe Dock and Railway Company purchased one rail mounted gantry (RMG) crane from ZPMC. Liftech reviewed the structural design, structural fabrication, and seafastening design and installation.
West Basin Container Terminal purchased four dockside container cranes from ZPMC for Berths 100-102 at Port of Los Angeles. Liftech provided the technical specifications, structural design and review assistance, and fabrication support for the new cranes. The design constraints for the new cranes presented a unique challenge. The new crane geometry is similar to that of the existing cranes, but the structure is designed to comply with new seismic criteria, which are more demanding for the crane structure.
In response to the community’s desire to preserve the marine view, Port of Los Angeles offered to consider low profile cranes for Berths 100–102. Liftech studies indicated that the conventional low profile cranes did not comply with the port’s seismic design standards for the wharves.
Liftech worked with VIT and ZPMC engineers to develop the elevating girder crane design. The upper works (including the trolley girder, boom, trolley girder support beams, A-frame, apex beam, and stays) may be hoisted to any of five preset elevations to reduce hoisting time to suit ship sizes. Liftech provided full procurement services for the project.
Four post-Panamax cranes were designed to meet specific requirements of Port Everglades, including strict aircraft clearance requirements and efficient structures to withstand hurricane winds. The inclined landside leg significantly reduced the weight. An improved adjustable boom hanger system increased reliability and enhanced boom travel performance.
Liftech provided the conceptual and final structural design and detail drawings for two post-Panamax low profile container cranes. The inclined landside leg significantly reduced the overall weight, reduced the wheel loads, and allowed for a lightweight boom.
Hanjin Heavy Industries provided three cranes for Hanjin Shipping’s new terminal in Kaohsiung. The cranes have an outreach of 52 m (170’-6”) and a rated load of 40.6 t (40 LT). Due to the nearby airport, the height at the terminal is restricted to 70.35 m (230’-10”).
